RFS deputy commissioner Rob Rogers said embers from the fire were impacting properties.

"It's throwing up loads of embers onto properties and basically people need to be vigilant. We're not advising people to evacuate right now because the fire is right at their back door," he told Macquarie Radio.

"Stand by on your property and obviously look for embers and look for firetrucks in your street if you have concerns."

Firefighters are on scene and are being assisted by a water bombing aircraft.
